C# Directory.Exists的代码示例

通过代码示例来学习C# Directory.Exists方法

通过代码示例来学习编程是非常高效的。
1. 代码示例提供了一个具体而直观的学习环境，使初学者能够立即看到编程概念和语法的实际应用。
2. 通过分析和模仿现有的代码实例，初学者可以更好地理解编程逻辑和算法的工作原理。
3. 代码实例往往涵盖了多种编程技巧和最佳实践，通过学习和模仿这些实例，学习者可以逐步掌握如何编写高效、可读性强和可维护的代码。这对于初学者来说，是一种快速提升编程水平的有效途径。


Directory.Exists是C#的System.IO命名空间下中的一个方法, 小编为大家找了一些网络大拿们常见的代码示例，源码中的Directory.Exists() 已经帮大家高亮显示了，大家可以重点学习Directory.Exists() 方法的写法，从而快速掌握该方法的应用。

Directory.Exists的代码示例1 - New()

    using System.IO;

        public void New()
        {
            tempFolder = Path.Combine(Path.GetTempPath(), Path.GetRandomFileName());
            int tries = 1;
            var baseFolder = tempFolder;
            while (Directory.Exists(tempFolder) && tries < 3)
            {
                tempFolder = $"{baseFolder}_{tries}";
                tries++;
            }
            if (tries >= 3)
                throw new Exception("Failed to create temporary folder");

            Directory.CreateDirectory(tempFolder);
        }
